Abstract: 1,107,849. Cosmetic stick holders. S. CHERBA. 17 May, 1965 [21 May, 1964], No. 20710/65. Heading B8P. [Also in Division F1] A plastics lip-stick holder 10 has a retractable protective sleeve 15 telescopically mounted within the body 11. A lipstick 14 is held in the seat 19 in the inner sleeve 17 of the body 11 which has an outwardly extending shoulder 24. The sleeve 15 has inwardly extending beads 27, 29. The body 11 and sleeve 15 are assembled by thrusting the parts together, the resilience of the parts permitting the flange 24 to snap past the beads 27, 29, the flange 24 and bead 27 forming a stop for the sleeve 15 in its extended position. The beads 27, 29 may be replaced by an annular wall portion. Reciprocation of the body and the sleeve is effected by interengaging a flange 31 and the notches 32 with the helical ribs 34. The flange 31 and shoulder 35 also provide a second stop for the sleeve 15. The sleeve 15 may be secured in its extended position by seating the flange (31) in the seat (33<SP>1</SP>) (Fig. 5, not shown). In the retracted position the sleeve is limited by the perforated 36 base 16. In a second embodiment the two-part lipstick holder has a retractable sleeve and body with flanges (55) and notches (56) engaging with the helical ribs (57), the bead (61) and base (42) acting as stops for the sleeve in its extreme positions. The projections guide the members (41), (47). The sleeve can be locked in its extended position with the flange (55<SP>1</SP>) in the seat (62) (Fig. 9, not shown). A third similar embodiment has helical ribs (84) on the body (71) (Figs. 10-13, not shown) which engages with the flange parts (95) and guide members (97), (99). The sleeve can be locked in its extended position with the flange in the seat (89) (Fig. 13). The above embodiments may be adapted to form a dispenser (Fig. 5A, not shown) for liquid or semi-liquid (104), the partitions (106), (105) being telescopically connected together and the reciprocating mechanism being similar to those used in the holders above. In all the above embodiments the plastics parts are assembled by thrusting the parts together causing the resilient flanges, shoulders and beads to snap into engagement.

Abstract: 121,487. British Westinghouse Electric & Manufacturing Co., (Assignees of Chubb, L. W.). Dec. 13, 1917, [Convention date]. Systems for alternating-current motors only.- In systems for the supply of a polyphase load from a single-phase supply, the secondary of the singlephase transformer is subdivided and sections are connected between the phase windings oi a dynamo-electric phase converter and the polyphase load, in such a manner that the phase sequence of the resulant electromotive forces of the converter is opposite to that of the electromotive forces generated in the phase windings of the converter and the electromotive forces of the polyphase load are balanced. In the arrangement shown in Fig. 1, power is supplied from a single-phase trolly line to a three-phase propulsion motor 17. The inner ends of the secondary windings 21, 22 of the single-phase transformer are connected to the terminals 1, 2 of the star-connected stator of the rotary phase converter 10. The outer terminals of the secondaries and the terminal 3 of the converter can be connected to the motor terminals by switches 27, 28, 29. The numbers of turns in the transformer secondaries and in the phase converter windings have the ratio #3 to 1 and the connexion produces a displacement of 120 degrees in the phase of the electromotive forces supplied to the motor terminals 6, 8. Under no-load conditions, the middle points of the windings 21, 22 are of substantially the same voltage and phase. These points may be joined when the polyphase apparatus is disconnected to make a circuit for keeping the converter in operation. A two-phase motor may be supplied in a similar manner. In a modification, Fig. 7, the connexions are for a sixphase motor 50 and a converter 40. The sections 57, 58, 59, 60 of the transformer secondary are connected between the converter windings 43, 42, 46, 45 and the motor.

Title: Optical viewing apparatus
IPC: G02B23/14
Filed: 1950-08-25
Abstract: 701,041. Optical viewing apparatus: photographic cameras. VOIGTLANDER & SOHN AKT.-GES Aug. 25, 1950 [Sept. 28, 1949] No. 21090/50. Classes 97(1) and 98(1) In optical viewing apparatus having a substantially opaque screen in the light path between an object and one eye of an observer, said screen incorporating a substantially transparent mask and a small transparent area or 'aperture having a single boundary, and an optical system so that said one eye of the observer sees an image of the mark superposed on the wide object field seen by the other eye and at the same time sees through the small area or aperture a restricted view of the object and receives therethrough one beam of a range-finder, the optical system consists of or includes an annular element or elements so that the beam passing through the small area or aperture is not reflected or refracted by the optical system. As shown in Fig. 4, the view-finder comprises an opaque screen having a transparent mark N and a central aperture D and lying in the light path between an object and the right eye R of an observer whose left eye views the whole object field. Through aperture D passes one beam of a range-finder which is combined at H with the other beam reflected at U and the combined beams pass to the eye through an aperture O in a lens K which also serves to form an image of the mark that appears to be superposed on the object. Lens K may be replaced by a pancratic optical system and a telescope, which may be pancratic, may be positioned in the light path between the object and the other eye. The apparatus maybe mounted on a photographic camera, Fig. 5, so that either eye Q can look through it. To eliminate parallax, the annular lens K is mounted on an arm C pivoted at E and movable over a scale G. The image of the mark may indicate the boundary of the image of the object formed on the film in the camera by an objective of certain focal length and in order that different camera objectives may be used each objective is mounted as a unit with the screen having the mark corresponding thereto. In Fig. 9, five camera objectives are mounted on a turret T and the arrangement is such that one eye L views the object through the lens (e.g. N4) which is adjacent to the photographing lens (e.g. N3) which the other eye R sees a restricted view of the object through the central aperture of screen M and also an image of the mark on the screen superposed on the object. The ratio between the focal lengths of neighbouring objectives is approximately constant so that the size of the image of the mark formed by lens K will be substantially correct for all the objectives. Screen N may be replaced by two relatively adjustable screens M<SP>11</SP> and M<SP>12</SP>, Fig. 10, whereby the size of the central area M<SP>13</SP> can be adjusted, for example, by the focusing mechanism of the camera. Specifications 454,064 and 639,409 are referred to.

Abstract: 221,805. British Thomson-Houston Co., Ltd., (Assignees of Hull, J. I.). Sept. 10, 1923, [Convention date]. Alternating-current commutator and induction machines; exciting.-In regulating systems cornprising a polyphase commutator machine concatenated with an induction motor, the field of the commutator machine is separately excited by a machine 5 having a polyphase exciting winding 16 connected to the secondary of the main motor, a second polyphase exciting winding 6 connected to the mains, and a commutator winding 10 inductively related to the exciting windings and supplying component voltages proportional to the ohmic and reactance drops of the field of the concatenated machine. The windings 6, 16 have opposite phase rotation and are non-inductive with respect to each other. The magnitude of each induced component is varied by shifting brushes 13 - - 15, 13<1> - - 15<1> connected to each phase in opposite directions, the phase of each component being adjusted by shifting all the brushes through a predetermined angle in the same direction, or by rocking the stator, or shifting each set of brushes at a different rate. The brush-moving mechanism includes a pinion meshing with concentric annular racks. In modifications, instead of distributing the winding 16, it may be concentrated in zones, and the number of slots on one side of the winding zones may be increased to vary further its exciting component.

Abstract: 391,755. Projectile fuzes. SOC. ANON. OFFICINE GALILEO, 24, Via Carlo Bini, Florence, Italy. July 28, 1931, No. 21560. Convention date, Nov. 14, 1930. Void [Published under Sect. 91 of the Acts]. Addition to 389,787. [Class 9 (i).] Relates to clockwork fuzes such as are described in the parent Specification, and consists in (1) an improved connection between the internal mechanism and the outer setting cap, and (2) an improved safety mechanism. The time disc g of the internal mechanism is connected to the outer cap b by an axial plunger d, which is slidably guided by keys a in the cap and is normally held up in the active position by spring blades e. In this position, lugs f on the plunger d interlock with the time disc g and transmit to it any rotational adjustment of the cap b. After the adjustment has been made, the plunger d may be pushed back by a gudgeon pin inserted through an aperture h, or may set back by inertia when the projectile is discharged ; in the retracted position of the plunger, the lugs f are disengaged from the time disc g, which can therefore be rotated freely by the clockwork. The lever arm i is provided with a spring tongue m bearing against the pawl l which rides against the time disc g. The spring tongue m must be stressed by a slight rotation of the sleeve n by its centrifugal drive t before a catch o on the sleeve n releases a pin p on the centrifugal safety device r. This delays the arming operation, which is further delayed by the provision of a slot s in the centrifugal safety device which must make a movement corresponding to the length of this slot before the firing-pin is freed in readiness for operation at the time for which the disc g has been set.

Filed: 1975-05-21
Abstract: 1501194 Developing photo-resists INTERNATIONAL BUSINESS MACHINES CORP 21 May 1975 [6 June 1974] 21878/75 Heading G2C A resist comprising a base soluble resin and a quinone diazide sensitizer is imagewise exposed, treated with hydrogen ions and then developed in an alkaline solution. The resist, which is normally positive working, is rendered negative working by giving it a blanket exposure subsequent to the hydrogen ion treatment. In this process the areas which become alkaline soluble during the first exposure are rendered less soluble by the hydrogen ions. The blanket exposure renders the initially unexposed areas more soluble and these are then removed during alkaline development. In an alternative process the blanket exposure is omitted and the resist, which is coated on a substrate, remains positive working. The developed relief image and uncovered substrate are coated with a metal e.g. aluminium, and the resist and overlying aluminium are lifted off using acetone, to leave the metal patterned substrate. The hydrogen ion treatment provides an improved resist profile. The resin and sensitizer are preferably a phenol-formaldehyde resin and a 2, 3, 4-trihydroxy benzophenone ester of 1-oxo-2-diazo-naphthalene- 5-sulphonic acid respectively. The hydrogen ions are provided by a mineral acid e.g. HCl or H2SO4.
